IRON STRUCTURE FOR OVEN-BUILDINGS.

Specification of Letters Patent.

Patented Sept. 29, 1908.

Application filed March 20, 1907. Serial N 0. 363,336.

To all whom itmay concern:

Be it known that I, KARL BERNHARD, a v subject of the Em ero'r ofGermany, and resident of Berlin, ermany, have invented certain new anduseful Improvements in Iron Structures for Oven-Buildings, of which thefollowing is a specification.

My invention relates to the iron structure of buildings or housescontaining ovens, or retorts which structure serves to support the roofas well as the bunkers and charging devices. Iron structures of thischaracter have frequently been carried entirely, or in part, upon theovens or their anchoring framework connected with such ovens orframework. Such rigid connection has in practice proved objectionable,on account of the motion of the oven or furnace, due to expansion andcontraction, this motion being transmitted to the iron structure andcreating therein injurious strains, which cannot be figured accurately,and in view of which the parts have to be made much heavier than wouldbe required otherwise, so that the advantage of using the oven orfurnace as a partial support is at least a very doubtful one. To avoidthese injurious additional strains, which in some cases may be muchgreater than the main strains due to weight, I have devised my presentinvention, according to which the iron structure is connected with theoven, or its anchoring framework, not rigidly, but loosely, or movably,so that the brickwork of the oven or furnace may move independently ofthe supporting framework of the building. The'vertically acting Weightof the roof and of the charging work of the roof, is borne directly bythe oven structure. The side walls of the building can be simply susended from the roof and thus a considerable economy can be effected, ascompared with the usual construction of such buildings.

In the accom anyin drawings I have illustrated severa embo iments of myinven- Figures 1 and 2 are a side view and end view respectively of anoven, which serves as the only support for the framework carrying thebunkers and the charging devices. Fi 3 illustrates a form of myinvention in whic the framework is connected with the roof structure.Figs. 4, 6 and 8' are side views of the joints employed by me betweenthe framework and the oven, and Figs. 5, 7 and 9 are correspondin endviews.

In Figs. 1 an 2 the oven or furnace a, which may be of any suitableconstruction, and consists of masonry or brickwork, carries on its u persurface a supporting framework 6 for tl fe bunkers and charging devices.This framework consists of several sections, linked together by pivotalconnections, as indicated in Fig. 1, so that each will to a certainextent move independently of the others. This framework b rests onrolling members, suchas balls, rolls, or roll segments 0, which may bejournaled or seated on the u per surface of the oven, or on theframework 1) itself.

Figs. 4-and 5 show u on an enlarged scale a construction in whic ballsegments 0 are loosely supportedon the upper surface of the oven a. Onthese ball segments the osts d of theframework I) rest by means of pates e, located at the lower ends of said rovided, if desired, withlateral flanges f. imilar lates are located on the upper surface oft eoven.

In Figs. 6 and 7 I have shown another construction in which the rollsegments 0 are pivotally supported on the oven and carry the posts dinthe same manner as previously described. In Figs. 8 and 9 the posts dare ivotally connected with roll segments 0 w ich are loosely supportedon plates e, resting on the upper surface of the oven in the same manneras in Figs. 4 and 5.

It will be seen that in each of these constructions the oven receivesthe vertical downward strain from the supporting posts d, but theseposts are capable of moving relatively to the oven, in case the lattershould ex and or contract in heating or cooling.

n Fig. 3 the supporting framework 6 is carried by the oven a in the samemanner as hereinbefore described, and has in addition a peculiarconnection with the roof structure 9 ,of the building h, allowing theframework 6 to move vertically, yet preventing its horizontal movement.For this purpose the framework 9 of the roof is provided at the innerends with rolls "5, engaging either the supporting posts d, or specialguide posts. Lateral stralns are thus transferred to the building it,while at the same time a sagging of the oven will have no influence onthe building it.

The supporting posts d, resting on the oven or on its anchoringframework loosely, as by means of balls, rolls, or segments of suchelements, will not follow the oven in any of its lateral movements, andthus detrimental stresses in the framework will be avoided.

I claim as my invention:

1, The combination with an oven, of a framework located above the oven,and roll ing connections interposed between the oven and the framework.-

2. The co1nbination,with an oven and the building wherein such oven iscontained, said building including a roof projecting above the oven, ofa supporting framework having a loose connection with the top of theoven l and arranged in guiding en agement with and between parts of theroo 3. The combination, with the oven, of a supporting framework restingon the oven and having a loose connection therewith, and

the building containing said oven and provided with a roof havingmembers projecting towards each other and in sliding engagement with thesaid framework to guide the same vertically.

4. The combination, with the oven, of a supporting framework restingthereon loosely and comprising sections connected with each otherloosely, so as to be capable of movement relatively to one another. Intestimony whereof l have signed my name to this specification in thepresence of two subscribing witnesses.
